Letters Patentvlvv'o. 88,617, dated April 6,1869; antedated Mci/rch 25, 1869.

The Schedule referred-to in these Letters Patent and making part of the same To all whom it nia/y concern Be it known that I, JUsTUs Donnino, of Philadelphia, Pennsylvania, have invented an Improved Bedstead-Fastener; and I. do hereby declare the following Yto be afull, clear, and exact description of the saine.

My invention consists of an inclined adjustable screw, secured to the side strip of a bedstead, in combination with a plate secured. to the post, and having a slot adapted to the head of the said screw, as fully described hereafter, thewhole forming a secure and tight bedstead-fastening in which there are no openings o1' interstices for the collection of insects.

Incorder t0 enable others to make and apply my invention,I I will now proceed to describe the Inode of carrying the same into effect, reference being had to the accompanying drawing, which forms a part of this specification, and in which- Figure 1 is a sectionalview of sniiicent of a bedstead to illustrate my, improvement;

Figure 2, a sectional plan view ofthe same on the line 1-2, i'ig. l; and

Figures 3 and 4.-, views of portions of the bedstead detached from each other.

VSimilar letters refer to similarl parts throughout the several views.

A and A' represent portions of the posts, and

B, the side-strip of a bedstead.

A screw, C, is inserted into each end of the sidest-rip B in an inclined'direction, as plainly shown in fig. l, the object of which' inclination is to cause the screw to cross the grain ofthe wood, sothat it shall haven .better hold, and be less liable to draw out than if inserted straight, and for additional security it may, if desired, be caused to pass through a pin, or block a, which is. driven transversely into the side-strip.

1t will be seen that the screw passes through the piu, or block a, iu a direction transverse to the grain ofthe latter, and is therefore retained much more firmly in its position thanlwould be possible if it passed merely into the end oft e side-strip, in a direction parallel, or nearly parallel, to the grain o f the wood, while it will also be apparent, that should the screw-threads in the -block become worn, so as no longer to afford a hold to lthe screw, the block may-be removed and replaced by another, inwhieh as rm a hold maybe obtainedas in the rst.

The head of each screw yprojects from the end of the side-strip,-and is adapted to a slot, l), formed in a plate, F, which is let into the bed-post, and secured to the same by screws c c.

The upper end of the slot b is sufficiently large to admit the 'head of the screw, but is narrowed toward its lower end, as shown in iig. 3,`and within this narrow 'portion of the slot are shoulders e e, having an inclina- 4figs. l and 4.

Beside the fastening above-described, one or more guide-pins, 7L, are secured to the ends of the side-strip, and are adapted to slotted plates i, secured to sides of the posts.

To fasten the side-strip and post together, all that is necessary is to insert the head of the inclined screw into the enlarged upper end of the slot b, and then depress the side-strip, the head of the screw bearing against thev inclined shoulders e e, and drawing sidestrip andV post together.

The guide-pins h h prevent all lateral motion of the posts or side-strip, and render the fastening secure, it being impossible to disconnect the partsexcept by raising' the side-strips, and the greater the weight upon the latter, the firmer will the fastening become.

The joints between the partsbeing entirely closed by the above arrangement, no cracks, or other openings are afforded for the collection of insects, and if, after long continued use, the fastening should become loose, it may be readily tightened by a proper adjustment of the screw C.

I claim as my invention, and desire to secure by Letters Patent- 1. A bedstead-iastener consisting of' a screw, C, and a hollow cylindrical block, F', having screw-threads on the outside,and within it a slot, b, and inclined shoulders e adapted to the head of the screw 0,:al1 substantially as and for the purpose described.

2. The combination ofa side-strip, B, a detachable block, a, passing through the side-strip and a screw, C, passing into the end of the side-strip and into the block a, as and for the purpose described.

In testimony whereof, I have signed my name to this specilication, in the presence of two subscribing witnesses.
